Abstract (en)
[origin: EP0857745A2] Production of block copolymers (A) containing (a) block(s) derived from polyarylene ethers (PAE) with units of formula (I) and anhydride end groups of formula (II), and (b) block(s) derived from polyamides with terminal amino groups, in which t, q = 0, 1, 2 or 3; T, Q, Z = a chemical bond or -O-, -S-, -SO2-, -SO-, -CO-, -N=N-, -RaC=CRb- or -CRcRd-; at least one of these groups = -SO2- or -CO-, and Z = -SO2- or -CO- if t and q = 0; Ra, Rb = H or 1-10C alkyl; Rc, Rd = H, 1-10C alkyl or alkoxy, or 6-18C aryl (all optionally substituted with F and/or Cl), or these groups plus the linking C atom may form a 4-7C cycloalkyl group which may also be substituted with 1-6C alkyl group(s); Ar, Ar<1> = 6-18C aryl, optionally substituted with 1-10C alkyl or alkoxy, 6-18C aryl or halogen. The process comprises reacting (a') hydroxy- and/or phenoxy-terminated PAE derived from units (I) with phthalic anhydrides of formula (III) (with X = F, Cl, Br or I) to form PAE (a), and then reacting (a) with polyamide (b) in the melt or in solution. Also claimed are (i) moulding materials containing (A), and (ii) mouldings, fibres or film obtained from these moulding materials.
